Select the appropriate law for each description:
some energy is released as unusable heat energy into the environment.
energy can only be changed from one form to another.
energy can't be created or destroyed.

The appropriate law for each description is as follows;  

Some energy is released as unusable heat energy into the environment - Second law of thermodynamics.

Energy can only be changed from one form to another - First law of thermodynamics.

Energy can't be created or destroyed – First law of thermodynamics.

The first law of thermodynamics, also referred to as law of conservation of energy, states that energy cannot be created or destroyed, but can only be converted or transferred from one form to another.

The second law of thermodynamics states every energy transfer that occur will increase the overall entropy of the universe and minimize the amount of usable energy available to do work.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
